Application and July 12,1904. Serial in. 216,269;

To (1 35 whom it may crmcerm Be it known that I, ARTHUR J. Brneos, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful 1m rovements in 'lypeWriting Machines, of w ieh the following is a specifics;- tion.

This invention relates to type-writing ma chines, and more particularly to the paperfeeding mechanism of such machines.

The main object of the invention is to provide means for regulating and facilitating the insertion and manipulation of the aper in the machine, said means consisting, t, ofe pa per-stop for the leading edge or sheet as it is introduced into the machine, said stop cooperating with the main food roll to secure uniformit in the positioning of the paper; second, egsge or guide tor the side edge ,of the sheet, said gage serv ing to position the sheet laterally; third, of

mechanisrn for separating from the surface of the platen both the main feed-roll and the paper-stop for the top or leading edge of the a er.

$0 this and other ends, which willv subsequently appear, the invention consists oi certain features of construction and combinations of devices, all as will be hereinafter set forth,

'- and more particularly pointed out in the hppended claims,

The invention is shown in the drawings as embodied in a Smith Premier type-writing machine; but it is to be understood that it may be adapted to other forms of writing-mechines.

One form of the invention is illustrated in the accompanying drawings. wherein-- Figure 1 is arear elevation of the platen and 'laten-frame of e type-writing'niaehine emodying the invention. Fi 2 is an enlarged fregnentary plan View of the right-hand end of ig. 1 as seen from the under side. Fig. 3 is a View taken on the line as a; of Fi 1. Figs.

r The same art will be designated iv the some sum in throughout the severe views of the dra i gs, in which- 1 is a. platen mounted upon a shaft 2, suptop of the.

ported in side bars 3 and 4, which are connectcd together by a front rod and rear rod 6, the side bars and the front and rear rods composing the platen frame. :tdjustshly mounted on the front rod 5 are the usual murginal spring paper-fingers 7, each having a.

rearwordly-extending end 8 and the front feed-rolls 9, of which only one is shown. Pivotelly supported near the ends of the rea rod fiarethe upper ends of depending links it}, the lower ends of said depending links serving as bearings for a small red or shaft 11. The ends of the rod 11 project beyond the hearings in the links 10, end to these ends are pinned or otherwise snitshiy secured the ower ends of the short links or arms 12, which ere(provided with eyes, so that they may be rea ily mounted u on the said rod 11. The upper ends of the inks or arms 12 terminate in eyes 13, in which the shaft 14 is fixed, and upon this latter shaft the main pressure or feed roll 15 is loosely mounted and is pinintained in its proper position longitudin. lly of the said shaft by means of the collars 1o. he left-hand end of the shaft 14, or, as viewed from the rear, as in Fig. 1, the right-hand end, extends beyond the eye 13 in the sup porting-link 12 and is provided with s handle or finger-iever 13', which is made fast to the shaft. Suitably secured, as by Set-screws, to the resr rod 6 are the'verticel standards or supports 18 of the pa er-table 19, and sttuohed to the backs of t iese supports are lea-fsprings 20, the lower ends whereof bear against the collars 16 with a pressure regulated in degree by the regulating-screws l3.

Pivotally mounted upon the shaft 11 and extending longitudinally of the platen is a pepenguxde plate .22, terminating at the rear in an outtnrned lip .23, which serves as a stop and regulator for the lending edge or top of the sheet to be written upon. The preferable manner of mounting the paper-guide plate and paper-stop upon the rod or shaft 11 1 sonsists, as appears most clesriy in Fig. 2, in

providing the under side of the plate '22 near its right and left hand ends with bearingplates 24. The bearing-pistes are suitably attached, as by rivets plate, forming, ter, ion bearing receive 25, to the paper-guide yes in which the shaft 11 is One f the rivets of each set,

as also appears 1 10st clearly in said Fig. 2,

in roniunotion with the lab serves'to attach a leaf-spring 26 to the under side of the bearing-plate 22 near each end of the latter, and the outer ends of said leafsprings bear a ainst bosses or projections 27 on the rear sur aces of the de ending arms or links near their lower en s.

The side edge or margin regulator for the sheet to be written u on is supported in a standard 28, which is s idably mounted upon 6 the rear rod 6 of the platen-frame, being maintainedin any desired position lon itudi- ,nally ofxthe platen by the spring 29, w iich is in frictional contact with the rod 6, as best appears in Fig. 6.- The middle portion of the top part of the support or standard 28 tenninates in a forwardly-turned lip 30, which hooks over the top of the paper-table 19, and thus serves to maintain the support in proper position vertically. The side top portions of the support terminate in eyes 31, wherein the' rod 32 is slidably mounted. The inner end of said rod is furnished with a ball 33, and the other end is turned forwardly at right angles to the main part of the rod, thus forming a stop 34 for the side edge of the paper. The rod 32 is flattened on two sides at 35 and 36 and may be turned back and down into non-working position, as shown by the dotted lines in Fig. l, the flattened portions 35 and 36 serving, in conjunction with a friction-spring 37, mounted at the back of the standard 28, to maintain the rod 32 in either of said positions. The friction-spring 37 also serves to retain the margin regulating rod 32 in position longitudinally of the platen, while the ball 33 and the stopportion 34 prevent the rod from becoming separated from its support. v

The method of using the means for regulating and positioning the paper and the action of the same will nowbe described. The normal position of the arts is best seen in Fig. 3, in which it will e assumed that the margin-regulating stop 34 is in the desired 45 relation with the laten, longitudinally considered. As will e seen upon an inspection of Fig. 3, the leaf-s rings 20, pressin in wardly against the co lars 16 on the fee( roll shaft 14, normally maintain the feedroll in frictional contact with the surface of the platen, while the shaft .14, pressing a ainst thedepending links or arms 10, under t e influence of the spring 20, tends to rotate said depending links 10 about their center upon the rear rod 6, pressing said links toward the laten to the position shown in said Fig. 3. n this position the forward end of the paperguide late 22, which is rotatably mounted u on the shaft 11, su ported in the lower ends of the de ending lin s .10, is pressed into con tact wit 1 the surface of the platen by the springs 26, and the stopping hp or ledge 23, in which the rear of the paper-gluide plate 22 terminates, is separated from t e laten. If 65 now preparatory to inserting the s eetto be written upon the fin er piece or lever 17, which, it will be recal ed, is fixedly attached to the feed roll shaft 14, be pushed rearwardly, the parts will assume the positions shown in Fig. 4-. During the first portion of the rearward swing or travel of the finger-lever 17 the shaft 11 is-swung about its axis of movement toward the laten, carrying with it the pivoted guide-p ate 22, the forward edge 0 the latter serving as a fulcrum." This movement is obntinued until the guideplate 22, which is bent to conform to the surface of the platen, is seated against the latter, the leaf-springs 26 yielding to permit the guide-plate to move sufficiently in advance.8o of the bosses 27 for this purpose. In this positi on, as will be apparent from an inspection of F g. 4, the paper-stop 23, which is integral with the uide-plate22, is in contact along its base with the laten. The shaft 11 having now reached t e end of its movement ti. ward the platen serves as a fulcrum for the supporting-links 12 of the feed-roll shaft 14, and the further rearward movement of the finger-lever 17 will cause the feed-roll 15 to be swung away from the platen about the shaft 11 as an. axis and against the tension of the sprin s 20. The parts will now be in the position diagrammatically illustrated in Fig. 4. If the sheet to be written upon (desi nated as.38 in said figure) be inserted, it Wfil pass down behind the platen until its leading edge or top contacts with the paper-stop 23. If the return movement of the finger-lever 17 be now be un, the feed-roll 15 will first be moved bac under the tension of its springs 20 toward the platen until it frictionally grips the sheet 38, after which the paper-stop 23 will move out of the ath of the leaitling edge of the sheet and wilfreturn with the guidelate 22 to the normal position. (Shown in Fig. 3.) It being presupposed that the sheet 38 has been inserted into the machine with its left-hand edge in contact with the marginregulating arm 34, the said sheet is now in position to be fed around the platen in the usual manner.

If it be desired. to advance or retract the sheet freely or to withdraw it altogether from the machine, the fin er-lever 17 is moved forwardly from norma position to the position shown by the dotted lines in Fig. 5, and this forward movement causes the parts to assume the positions illustrated in said figure, the feedroll 15, the guide-plate 22, and the paperstop 23 all being revolved rearwardly away from the platen about the back rod 6 as an axis, the guide-plate 22 forcin the front marginal aper fingers 7 to t e ositlon shown. he a er may now be wit drawn readily, and if tEe front side feed-rolls be. swung out of contact with the laten 1n a manner well understood an entire y free as e circumferentially of the platen wil be It will seen'that I provide means for gar-piece for moving the paper stop and feed- 65.! straightemn or squaring the leading edge or ,roll, the feed-roll and the paper-stop both be- 'toptof the s set as it is introduced into the 'ing revolubie about the same axis, the said Ina e for frictionally gripping orcontrolmeans being ada ted to move the feed-roll ,5; 1mg; the same while it is maintained thus against the sheet 0 as to frictionally centre If stral htened or squared and for at the same it and afterward to move the papef-stop out 7'0 time mgmg the sheet into a redetermined of the path of the leading edge of the sheet,
